The team Magma hideout can't actually be found unless you have a Magma Emblem, which someone (I can't remember who exactly it it is) will say they found it on the ground. Then you go to Jagged Pass and the Emblem will have a chain reaction with this certain spot on the Jagged Pass and the hideout will open.
There is no magma amulet in ruby. The location in which team magma's hideout is actually is the place where team aqua's hideout is in sapphire and emerald (i think you confused sapphire with emerald)
No only in aqua's hideout.
Judged Pass
near team aquas hideout in sapphire. but in emerald it is on MT. chimeny
On Mt Chimney to find it you need a magma emblem which you will get on Mt Pyre.
There is a master ball in the Team Magma's hideout in Pokémon Ruby Sapphire, and Emerald. Look in the Hoenn region for the Team Magma's base of operations.
you will go to lavaridge town again from cablecar and then go to south the ground will shake and there will be a hole and you will enter the magma hideout
